GUN WITH REGOILIN G BARREL.

Specification of Letters Patent.

Patented Dec. 12, 1916.

To all whom it may concern:

Be it known that I, KARL V6LLER, engineer, a subject of the German Emperor, residing at' 12 Scharnhorststrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Guns with Recoiling Barrels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a gun having a recoiling barrel and has for its object to arrange the trunnions of a gun of this kind in such a position that no part of the recoiling system in recoiling passes beyond the trunnions.

An embodiment of my invention is shown on the accompanying drawings in Which Figure 1 is a side elevation of -a gun constructed according to my invention. Fig. 2 is a plan view. Fig. 3 is a cross section in the line 3-3 of Fig. 1.

The gun barrel a is movable in a well known manner within the cradle 01. and may be elevated about the trunnions b resting in bearings 0 connected with the gun carriage cl. The latter rests on the platform e and is provided with an elevating mechanism f of any known construction. The gun carriage is provided with a vertical pivot g engaging a corresponding bearing in the platform so that the gun carriage with the gun may be adjusted in a lateral direction by means of the mechanism 9 Fig. 1 shows by dotted lines the gun in different positions of elevation and it will be seen' that the angle of elevation may be from 0 to 90.

The described arrangement has the advantage that the trunnions may consist of a single bolt 12 passing through both bearings 0. It is evident that the recoiling power is.

at all elevations of the gun always directed exactly toward the axis of the trunnions, and if'the trunnions or the bolt 5 are arranged at a small height over the platform 6 the re coiling power is always directed nearly toward the same point of the platform. Thereby it will be possible to make the platform very rigid and strong against the force of the recoil without unduly increasing its weight. n.

The pivot 9 may be arranged immediately below the point resisting the recoiling power or at least in the neighborhood of that point, so that the chief resistance point is always nearly at the .same place even when the gun has been' swung about a' large angle in a horizontal direction.

My invention is especially adapted for guns in which the platfornymay be transported in connection with the gun barrelor separated therefrom. However my invention is also applicable to guns having a fixed position or to guns with a wheel carriage.

Having thus described my invention what I claim is 1. In combination, a recoiling barrel, a cradle therefor, and trunnions for the cradle located in rear of the limit of travel of the barrel in recoiling and in the plane of the travel thereof.

,2. In combination, a recoiling barrel, a

cradle therefor having extensions theends vof which are beyond the limit of travel of the barrel in recoiling, and trunnions for,

said extensions at theouter ends thereof, the axial line of said trunnions being intersected by the axial line of said barrel'jllv allj positions of the latter.

3. In combinat1on,.a recoiling barreL-faj cradle therefor having extensions the-ends of which are beyondthe limit of travel oil:

the barrel in recoiling, and trunnions for said extensions at the outer ends, thereof, a carriage having bearings for the trunnions,

and a vertical pivot for the carriage, in ap-- proximately the same vertical plane with said bearings. 4. In combination, a recoiling barrel, a

the travel thereof, a carriage having bearfor'the carriage located in proximity to" the pivot of the cradle:

. 5. Ina-gun having a recoiling barrel'the combination of a cradle, lateral 'g'uide'ways ings for the trunnions, and a'vertical pivot connected with the cradle for guiding the 'recoilin barrel and trunnions at the outer.

end of t ese lateral guidewa-ys, the common 1 plane of the latter intersectingthe axiall'i line of said trunnions. p

6. In a gun having a recoiling barrel the In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

KARL voLLER.
